ABSTRACT
INTRODUCTION: Although nutritional treatment is an established pillar of multidisciplinary care provided in critical illness, there are many concerns regarding this issue in severe COVID-19. This observational, retrospective, multicentre study aimed to analyse the approach to nutritional treatment among selected intensive care units (ICUs) in Poland. MATERIAL AND METHODS: The medical records of 129 patients hospitalized in five units due to respiratory failure following COVID-19 were analysed in terms of nutritional management on the eighth day of the ICU stay. The Harris-Benedict equation (HB), Mifflin St. Jeor equation (MsJ) and ESPEN formula (20 kcal kg -1 body weight) were used to estimate the energy target for each patient, and two ESPEN formulas determined the protein target (1 g kg -1 body weight and 1.3 g kg -1 body weight). RESULTS: Evaluation of nutritional therapy was performed in 129 subjects. The fulfilment of caloric requirement considering the HB, MsJ and ESPEN formula was 66%, 66.7% and 62.5%, respectively. Two clinical centres managed to provide 70% or more of daily caloric requirements. According to the ESPEN formula, the implementation of the protein target was 70%; however, one of the investigated units provided a median of 157% of the protein demand. The nutritional management varied in the preferred route of nutrition administration. Neither method nor grade of nutrition supply influenced biochemical parameters on the 8th day of ICU stay. CONCLUSIONS: Significant differences in nutritional treatment of critically ill COVID-19 patients in Polish ICUs were noted, which underlines the importance of setting up clear guidelines regarding this issue.

Medical nutrition should be tailored to cover a patient's needs, taking into account medical and organizational possibilities and obstacles. This observational study aimed to assess calories and protein delivery in critically ill patients with COVID-19. The study group comprised 72 subjects hospitalized in the intensive care unit (ICU) during the second and third SARS-CoV-2 waves in Poland. The caloric demand was calculated using the Harris-Benedict equation (HB), the Mifflin-St Jeor equation (MsJ), and the formula recommended by the European Society for Clinical Nutrition and Metabolism (ESPEN). Protein demand was calculated using ESPEN guidelines. Total daily calorie and protein intakes were collected during the first week of the ICU stay. The median coverages of the basal metabolic rate (BMR) during day 4 and day 7 of the ICU stay reached: 72% and 69% (HB), 74% and 76% (MsJ), and 73% and 71% (ESPEN), respectively. The median fulfillment of recommended protein intake was 40% on day 4 and 43% on day 7. The type of respiratory support influenced nutrition delivery. A need for ventilation in the prone position was the main difficulty to guarantee proper nutritional support. Systemic organizational improvement is needed to fulfill nutritional recommendations in this clinical scenario.
